1. Getting into Medical School is next to impossible.
Besides needing to be a genius and a social pariah amongst your non-pre-med peers, you also need to a proven ability that you have another talent that you could potentially pursue if medicine does not work out for you. These include and are not limited to: NCAA volleyball champion, Canadian Idol finalist, and Professional violinist.
2. Getting into a Residency program is harder.
Remember your one medicine interview when you thought 'I dont care what I do, or where I go, I'll do anything to get in?' And then you get in and realize just how much the idea of spending the rest of your life looking at people's rashes, or cutting people open, might actually make you jump off a building. And then comes the realization that the idea of living anywhere could actually mean living in a city that'll make your eyes bleed. In Canada, we call this process CaRMs.
CaRMs is 6 months of anxiety leading up to a certain date and time when a computer system spits out where you are going to be and what you're going to be doing for the rest of your life. For most people, things do work out, but up until that point, it is probably the most stressful experience of peoples lives in medicine.
